What functions and functions of solar inverters in practical applications

         The main function of the solar inverter is to convert the battery DC into alternating current, through the full bridge circuit, mostly using SPWM processor through modulation, filtering, boost and so on with the lighting load frequency, （spannungswandler）rated voltage to match the sine AC For the system end users. This article will introduce the solar inverter in the practical application of what function and role.Maximum power tracking control function         The output of the solar cell module is changed with the solar radiation intensity and the temperature of the solar cell module itself (chip temperature). The voltage of the solar cell module decreases as the current increases, so that the maximum power can be obtained. Solar radiation intensity is changed, obviously the best task point is also changing. With regard to these changes,（230v strom） the task point of the solar cell module is always at the maximum power point, and the system has always obtained the maximum power output from the solar cell module, which is the maximum power tracking control. The biggest feature of the inverter used in solar power systems is the maximum power point tracking (MPPT) function.Active operation and shutdown function         With the slow rise of the sun, the solar radiation intensity gradually strengthened, the output of the solar cell also increases, when the inverter task to achieve the required output power, the inverter is active start. After the operation, the inverter will always take care of the output of the solar cell module. （wechselrichter）As long as the output power of the solar cell module is greater than the output power required by the inverter task, the inverter will continue to operate; until the sunset stops, The variable can also run. When the output of the solar cell module becomes smaller and the inverter output is close to zero, the inverter constitutes a standby mode.Other functions         Solar inverter not only has the maximum power tracking control function and, active operation, shutdown function, also includes the active voltage adjustment (grid system), anti-operation alone (grid system), DC ground detection (grid System) DC detection (grid system) and other functions.
